A Texan lands in Sydney, and is picked up by a taxi.
After requesting a tour of the city, he starts into a tirade about the small town airport and how in Texas they have larger runways on their ranches.
They are soon crossing the Sydney Harbor bridge, and the man is further unimpressed -- "I have a duck pond bigger than that harbor, and an ornamental bridge to span it that makes this look like a toy".
The Sydney-Newcastle expressway also gets his scorn, "Is this a road, or a track?"
So when a kangaroo jumped out in front of the cab, causing the sudden and severe application of the brakes, the driver couldn't help himself -- "Stupid grass hoppers!"
